Dealing with food cravings from antipsychotics when you can't buy food?

I can’t just eat whenever I want but it’s torture to think about food until i eat. I’ll eat myself out of house and home. Meds that don’t give you the munchies possible? Currently on risperdal

I’m currently taking Saphris and haven’t had any weight gain or munchies with it. Abilify and Geodon are supposed to be the best for no weight gain but I couldn’t tolerate them ; they both gave me anxiety and I couldn’t sleep. I think everyone is different.
